The purpose of the present work was to integrate the EndoScout tracking technique into a multi-slice interactive real-time sequence to assist MR guided interventions. The sequence was modified to provide the excitation gradients fed into the Endodoscout system for sensor tracking. The position and orientation of the surgical device is real-time updated and superimposed either on pre-acquired images or real-time images during the procedures. The multi-slice real-time images were displayed to enable both surgical device guidance and underlying tissue monitoring. Animal study suggests that MR guidance using the integrated system is feasible and effective at performing interventional procedures.
